ABSTRACT

 

 


Zangeneh MM, TahvilianR, Najafi F, Haghnazari L, Zangeneh A., Effect of hydroalcoholic extract of Scrophularia striata on Escherichia coli O157:H7 (ATCC No. 25922), Onl J Vet Res.,  20(12):761-767, 2016. Scrophularia striata (SS) has been used as an antioxidant, antiparasitic, antifungal, antiviral, and antiflammatory agent. Minimum inhibitory concentration (MIC) of SS hydroalcoholic extract on growth of Escherichia coli O157:H7 (EC) (ATCC No. 25922) on agar disk, well diffusion and macrobroth tube test was ~0.031 g/ml. There were discrepancies in sensitivity to SS: In agar disk diffusion there was no inhibitory effect at 0.007 g/ml and in agar well diffusion test, no inhibitory effect at 0.007 or 0.015 g/ml. 

 

Keywords: Scrophularia striata; Hydroalcoholic extract; Antibacterial activities, Macro-dilution method, Agar disk diffusion method, Agar well diffusion method.
